Rules that apply.

Limits vary by jurisdiction. These are the levers that decide what fits on your lot — we confirm every one of them against your city before design starts.

  • Height & setbacksSet by zone
  • SetbacksSet by zone
All the rules that apply, with citations
  • Structural reviewRequired for second storeys

These are the reviews and limits that typically govern this work. Most are set by your jurisdiction and by the building, fire and accessibility codes — they are requirements, not starting points. We confirm exactly which ones apply to your address and scope before design starts. See regulations by city. Statutes reviewed 4 August 2026.
